Matangini Hazra (1870 – 1942) was an Indian independence activist who participated in the freedom movement against British colonial rule in India.

Born in the village of Hogla in the Midnapore district of Bengal, Hazra became involved in the freedom struggle at a young age. She actively participated in the Indian National Congress and other nationalist organizations.

Hazra gained prominence during the Salt Satyagraha in 1930 when she led a procession of several hundred volunteers to picket the Tamluk police station in defiance of British salt laws. She was arrested multiple times for her involvement in various acts of civil disobedience.

One of the most notable incidents in Hazra's life was her participation in the Quit India Movement of 1942. At the age of 72, she led a procession of freedom fighters carrying the Indian national flag towards the Tamluk police station. Despite being unarmed, she continued to advance despite warnings from the police to stop. Hazra was shot by the police and succumbed to her injuries, becoming a martyr for the cause of Indian independence.

Matangini Hazra's courage and sacrifice inspired countless Indians to join the struggle for freedom. She remains a revered figure in Indian history, symbolizing the strength and resilience of the Indian people in their quest for independence.
